In the design of PCB, the ESD resistance design of PCB can be realized by layering, proper layout and installation. In the design process, most of the design modifications can be limited to the increase or decrease of components by prediction. By adjusting PCB layout and wiring, ESD can be well prevented. Static electricity from…
In PCB assembly and processing, PCB will be inspected and tested before processing to select PCB meeting SMT production requirements, and unqualified PCB will be returned to PCB manufacturer. Specific requirements of PCB can refer to IPC-A-610C international general assembly standard of electronic industry. The following are some basic requirements of small-scale SMT assembly processing…
PCB: “you want to change the scheme? Brother, I just laid out the device.” Overall: “the original solution really needs to be changed. Considering the heat dissipation, the package needs to be changed. Your current layout needs to be modified! “ PCB: “this board can’t fit into the layout at all!” Overall: “I let it…

SMT stencils from PCBSky are manufactured using laser technology, which ensures a constant process quality through its high level of precision. Our SMT Stencils fulfil the most stringent quality requirements with optimal register accuracy and cutting precision. The precise axial…
After PCB design, the most important step before PCB production is to export Gerber file.There are three versions of the existing Gerber file: Gerber x2: the latest Gerber format, which can insert layer information and attributes of boards; Extended Gerber (rs-274x) is widely used; The standard Gerber, or rs-274d, is an old version, which is…
Recently, the high momentum of the electronic industry has been transmitted to the PCB field. With the coming of the end of the year, the global inventory peak season is coming, and the demand accumulated in the first half of the year will be released in the second half of the year. Moreover, overseas orders…
The IPC (Association Connecting Electronics Industries) is a widely recognized organization that develops and publishes standards related to the design, assembly, and manufacturing of electronic products, including PCBAs (Printed Circuit Board Assemblies). Here are some of the important IPC standard documents related to PCBA electronic products: IPC specification catalog – PCB assembly IPC/EIA J-STD-001C Requirements…
In life, what products need to use PCB? The first is the electronic products that need integrated circuits In order to save space, make the products lighter, more durable, and achieve good performance, it is necessary to replace the previous wire connection to the printed circuit board. PCB can meet the requirements of space, performance…
With the increasing speed of electronic signal transmission, more and more products choose to use high-speed PCB substrate. What is high speed plate? “High speed PCB substrate” is commonly known in the industry, which generally refers to the low loss materials used in high-speed PCB. This kind of material has smaller DF (dissipation factor) than…
Layout is a boring and painful thing, but for an engineer who pays attention to layout, he can always get incomparable satisfaction and sense of achievement from the results in the end! In fact, PCB layout is like building a house. Every brick and tile needs to be manufactured and moved manually. I remember that…
Generally speaking, the conductive pattern made of printed circuit, printed component or combination of the two on the insulating substrate is called printed circuit, while the conductive figure providing electrical connection between components on insulating substrate is called printed circuit. 5G PCB not only has strict requirements on the reliability, electrical performance, thermal performance and…
The solderability of circuit board hole affects the welding quality The bad solderability of circuit board holes will produce false soldering defects, which will affect the parameters of components in the circuit, and lead to the instability of multilayer PCB board components and inner wires, which will lead to the failure of the whole circuit…
In order to meet the requirements of customers, the through hole of circuit board must be plugged. After a lot of practice, the traditional aluminum sheet plug hole technology is changed, and the solder mask and plug hole on the circuit board surface are completed with continuous plug and printing. Stable production and reliable quality.…
Ceramic substrate is a special process board that copper foil is directly bonded to the surface of alumina (Al2O3) or aluminum nitride (AlN) ceramic substrate (single or double sided) at high temperature. The ultra-thin composite substrate has excellent electrical insulation performance, high thermal conductivity, excellent solderability and high adhesion strength. It can etch various patterns…
Intelligent wearable products as a more popular form of products in recent years, more and more people pay attention to it. Although it can’t be accepted by all people, it does make some changes in the electronic product market. An intelligent wearable product is usually composed of RF circuit unit, clock circuit unit, memory circuit…
